SN03A is a high power factor flyback PWM controller special for lighting applications.
SN03A features an internal start-up timer for stand-alone applications, an analog multiplier with for power factor correction (PFC), zero current detector (ZCD) to ensure TM operation, a current sensing comparator with built-in leading-edge blanking, and a totem pole output ideally suited for driving a power MOSFET.
SN03A offers great protection coverage including system VCC under voltage lockout (UVLO),VCC over voltage protection, Cycle-by-cycle current limiting, and gate drive output clamping for external power MOSFET protection.
